3 Description of the device

3.1 Mode of operation

The device converts the DC voltage generated by the PV modules into AC voltage and feeds it into the power grid. The starting

procedure begins when there is sufficient sunlight and a minimum voltage is present in the device. The feed-in process begins

once the PV generator has successfully passed the insulation test and the grid parameters are within the requirements

imposed by the grid operator for a specific monitoring time. If, as it gets dark, the voltage drops below the minimum voltage

value, feed d the device switches off.-in mode ends an

2 -The “Max. input current” is the maximal theoretical value for operation with full power when the feed in power is low.

The inverter switches to the maximum AC output power.

The “Max. short-circuit current (ISCmax.)” together with the open circuit voltage (UOCmax) defines the characteristic of the

connected PV generator. This is the relevant value for string design and represents the absolute maximum limit for

inverter protection. The connected PV generator must be designed in such a way that the maximum short-circuit current

is less than or equal to the ISCmax of the inverter under all foreseeable conditions. The design must in no case result in a

short-circuit current greater than the ISCmax of the inverter.

generator power

Imax: Depending on PV generator

The input current from Chapter 4.1 7 on page is different for each MPP tracker and must not be exceeded. Therefore,

pay close attention to whether this value applies to PV1 or PV2.

7.5.4 Connection in parallel operation

Possible connection

Both MPPTs must be connected individually to the generator junction

box.

The DC inputs can therefore also be connected in parallel.

Only lines with the same MPP voltage may be connected in parallel

(Un1 =Un2=Unx)

Number of modules per string:

If the MPP trackers are used in parallel operation, the maximum

permissible power is 1.1 times the nominal power. In addition, the

maximum MPPT current is limited by the lowest value of all MPPTs.

For example, if the 15 kW inverter is used in parallel operation, the

maximum permissible power is 1.1x 15 kW = 16.5 kW and each MPPT

current is limited to 20 A (since one MPPT is rated for 32 A and the other

for 20 A).

7.5.5 Designing the PV generator

CAUTION

Damage to components due to faulty configuration!

In the expected temperature range of the PV generator the values for the no- -load voltage and the short

circuit current must never exceed the values for Udcmax and Iscmax in accordance with the technical data.

› Observe limit values in accordance with the technical data.

NOTE

Type and configuration of the PV modules

Connected PV modules must be dimensioned for the DC system voltage in accordance with IEC 61730 Class

A, but at least for the value of the AC grid voltage.

NOTE

Dimensioning the PV generator

The device is designed with a reserve of DC short-circuit current resistance. This allows for oversizing of the

connected PV generator. The absolute limit for the PV generator is the value of the max. short-circuit

current (lsc max) and the max. no-load voltage (Uoc max).

1 Network communication

Blue LED lights up and indicates the communication status between the

communication unit (WiFi stick) and a local network (router) or the

connection to the web portal or client (data logger, EMS...).

Blue LED flashes. The communication unit is connected to a local network

(router) but does not yet have an active connection to the web portal or client

(data logger, EMS...).

Note: For AP network configuration, you must be connected to the device’s

local WLAN network to re-enter the router information. The password for the

local WLAN network is the registration key found on the label on

communication unit (See Fig. 50).

Blue LED is off: The communication unit is in AP mode. The communication

unit forms a hot spot for a direct communication connection. Reasons for this

could be:

• The communication unit has not yet been integrated into a local network.

• The communication unit was integrated into a local network but could not

connect to the local router within 100 seconds (e.g. WiFi connection or bad

incorrect access data).

Note: After the 100 seconds have elapsed, the communication unit switches

to AP mode for 30 minutes and forms a hot spot for direct communication

connection. In AP mode, it is possible to carry out the network configuration

again.

2 Device communication

The green LED lights up. The LED indicates the communication status between

the communication unit and the inverters connected to the RS485 bus.

• The communication unit has an active connection to all inverters that are

stored in the communication unit.

The green LED flashes. This has the following cause:

• Reset, restart or firmware update of communication unit in process.

• Not all inverters stored in the communication unit are accessible.

The green LED is off. The communication unit has no connection to all

inverters known to it that are connected to the RS485 bus.

This has the following cause:

• Communication unit has no voltage supply

(DC voltage at the inverter too low or DC switch OFF).

RS485 bus connection to all known inverters interrupted.
